do u think a doctor will see me?

Im a 21 year old single women and stable as far as life goes. I have pcos. Im thinking about having a baby on my own through sperm donor. Im not very fertile as Is so im thinking about having a baby now before my ablity to have kids is gone. Its my dream to be a mother but I feel like if I dont chase that dream now I may never experience that. Ik it will mean I'll probably make myself alone for a long time but I found Im not really a relationship person, every single relationship I've had has gone sour on me. I have my moms support. Im just worried if A doctor would even see me with my age being so young? would any one know anything about that?
